WARNING: the –test option is deprecated. You can pass a script name or path on the command line without any options. WARNING: –max-time is deprecated, use –time instead sysbench 1.0.17 (using system LuaJIT 2.0.4)
Running the test with following options: Number of threads: 1 Initializing random number generator from current time
Extra file open flags: (none) 128 files, 1GiB each 128GiB total file size Block size 16KiB Number of IO requests: 0 Read/Write ratio for combined random IO test: 1.50 Periodic FSYNC enabled, calling fsync() each 100 requests. Calling fsync() at the end of test, Enabled. Using synchronous I/O mode Doing random r/w test Initializing worker threads…
